CF, describing an escort who is a boy in runner's juvenile mind, runs through blogs boldly. We called this new physical experience as 'Blog CF'. Many bloggers who sympathized with a boy set up widgets for 'Blog CF'. And those actions appeared as pieces of a colourful path which is a main motif at the campaign site. From there you can run again at any time with 'Blog CF'. The campaign site appeals to a 'boy' alive in every grown-up with contents, BGM, animations and so on all of which are both good old and bold.
